IMPROVEMENT IN WATER-WHEELS.

The Schedule referred to :in these Letters Patent and making part cf the same To-all whom it may concern ence being had to the accompanying drawings, and

to the letters of reference marked thereon.

. ,""lhe nature of my invention consists' in so constructing awheel, water-case, and adjustable ports, that the quantity of water applied .to the wheel may be varied, without breaking' the head or injuiing'the form of the parts through which the water is applied to the wheel. 'llo enable others skilled in the art to make and use my invention, I will describe its construction and op` eration.

Figure l isa vertical front viewpall set up, and showing thewatergate where the wateris admitted into thev case, and a portion' of the wheel.

L Figure 2 is a top view of the water-case, which coverst-he wheel and ports'.

Figure 3 isa sectionot" the wheel and adjustable poxt's, showing how the water is pitchedinto the wheel through the ports on line a.

' -Figure 4, on an additional sheet, is a vertical section of the whole, `set up audsplit through the centre. I construct my water-wheel with two bevelled rims,

Y b c, Iunited by twelve ellipse-curve paddles, It h h, fixed between the rims -b c, in suchan. angle as *to take up their length and have their ends flush with the rims inside and out.

I make -the bottom rim b with arms, and a hub to admit a shaft, g, through the centre, and' I make 4the top rim c enough larger than rim b to taper the wheel Vdownward six inches to the foot, or three inches to the foot all around it, thus producing what I call a flaring wheel.

I bevel the rims to face'at right angles with the taper ofthe wheel, and proportion itrby the following scale, which may answer't'or all sizes:

Il get the breadth of therims by taking one-ninth ofthe outside diameter of' top c. I get the breadth of the paddles It h by taking one-sixth ofthe outside diameter of the top rim c; and I get the length ofthe paddles'by taking one-third of the inside diameter of the top rim c.

A, at tig. 4, is a square frame, consisting oi' four flat sills, united, at the corners, with four upright pillars, shown by dotted lines, for the water-case to rest u'pon.

Bis a bridge-tree, regulated and secured at each end, by set-screws, to frame A. Said bridge-tree has asocket in the middle, holding astep-stud, on which shaft q turns, and so supports the weight ofthe wheel.

I construct the water-case P I with around curb, having a flange at its base, which coversthe wheel and puits, and rests upon the pillars of frame A. I make au opening in the curb ot' the water-case, and arrange thereto a horizontal slide-gate, operated by a rack-pinion and shaft, whereby the water isA admitted into or shut out of the water-case.

E E is' the cap o'r dome to the water-case, having, at its top, an oblong square box, containing a pair of boxes adjusted to shaft g.

I construct the adjustable ports by two convex flanges, -n o, both having sectional rims, or rims with pieces cut out of them, the bottoni flange o being permanently secured to the base of the water-case, and thus constitutes its bottom, said de nge o having a hub,

m, which passesl up through the collar of-flange' 11,-' flange n being 'Vmadeto work freely Within the other,

o, and both being employed in forming tapering ports by each having. wings spreading apart as they extend inwardly. 'Flange nbeing operated by rack L, pinion R, and shaft S, thereby the ports can be expanded or contracted without injuring their shape.

z z is a tube, connected to m below and dome above, tokeep the water from the shaft g. A

Alhe gate by which the water is admitted into the `case should be thrown wide open when the wheel is running, in orde-r to have the full pressure of the head in the case.

That I claim as my invention, 'and desire to securel by Letters Patent, is-

--The flaring wheel,rwith ellipse-curve paddles, to which the-water is applied inside, and discharges'outside, in combination with the trame and water-casa having adjustable ports, substantially as shown and described.
